General
Cetetherm AquaEfficiency is a compact tap water system product including a heat exchanger, motorised
control valve and managed primary and secondary pumps, as per versions. It is equipped with a control box
including a dedicated PCB and communicant temperature controller. Piping is made of specially designed steel
and brass parts.
AquaEfficiency has been tested hydraulically and electrically at the factory.
The tap water module is designed for indoor installation in plant rooms where the ambient temperature always
should be above 0°C. Max ambient temperature: 40°C. Max. hyg: 85% without condensation.
When handling the unit, make sure the actuator and its wire are not damaged or stressed.
The charging pump will be mounted when installing the AquaEfficiency.

Operating principle
AquaEfficiency EFF76 / EFB112 DD
AquaEfficiency EFP 5000/7000 DD
•8The primary water enters the control valve with actuator (A) and leaves through the fitting (B).
•Cold water enters at bottom part (CW) and leaves at the required temperature at high part (DHW).
•The primary circuit is equipped with a single or double pump.
•The secondary circuit should be equipped with a recirculation or a charging pump for
Direct (Instantaneous) versions.
Indirect versions (Semi Instantaneous) are equipped with single or double secondary pump.

Installation of an AquaEfficiency unit
The installation work must be carried out by an authorized installation contractor.
The temperature and the pressure of the water are very high. Only qualified technicians are
allowed to work with the AquaEfficiency.
Incorrect operation may cause serious personal injury and result in damage to the building.
Minimum pressure/temperature on primary side: 1.0 bar at 7°C, 1.5 bar at 100°C
Maximum pressure/temperature on primary side:10 bar /100°C
Minimum Pressure / Temperature on secondary side: 1.0 bar/ 7°C,
Maximum pressure / Temperature on secondary side: 10 bar/ 100°C
3.1 Unpacking/preparation/mounting
•Before installation this manual must be read.
•The system should be installed and connected in conformity with standard flowcharts defined in
4 Flowcharts.
•Rinse the pipes, before connecting them to the tap water module.
The pipe work may contain solid particles that could block or prevent the control valve with actuator to
operate correctly.
•Check the tightening dimensions of the gasket and plate heat exchanger (GPHE), see measure table in
18.1 Clean the plate heat exchangers (P-series).
•Also check:
oAir vent position
oSettling pot presence on primary side
oBoiler installation and capacity conformity
oPressure breaker (primary vessel, mixing bottle or equivalent) presence on primary side
oBalancing valve on secondary side of indirect (semi-instantaneous) installation
oAccessibility of unit and components
•Pipe the primary and the secondary side of the module.
•Fill-up both sides progressively with water.
•Purge air at high parts.
•Purge all the pump bodies.
•Install electrically the unit respecting electrical installation information see chapter
8 Electrical installation and 18.13 Technical data.
•Switch on the power.
•Check controller setting and enable the required functions.
3.2 Commissioning
The controller has been set at the factory. If any function needs tuning, values can be changed with reference
to this manual for parameter setting. Initially, the commissioning process should be carried out with the factory
settings.
Fill out the form in chapter 21 Commissioning report.

Installation, service and operating instruction

Flowcharts
The tap water modules should be installed according to the following schematics.
Whatever type, unit model and production type (Instantaneous or Semi Instantaneous), each
pump (or pump motor when double ones) delivers 10% to 100% of the nominal primary pump
signal and 25% to 100% of the nominal secondary pump signal, to stick to the actual demand.
Cetetherm do not recommend the use of a mixing bottle on primary side of an AquaEfficiency installation,
because the mixing effect destroys the low return temperature. But the need for the differential pressure
breaker functionality of this mixing bottle is still mandatory.
On AquaEfficiency Cetetherm recommends replacing the traditional mixing bottle by a small buffer tank, named
STBI, that serves as an inertial storage tank and avoids any boiler pumping.
In case a primary vessel, named STP, is required or designed on the installation, the STBI tank becomes
unnecessary.

Installation of an AlfaPilot unit
5.1 Operating principle AlfaPilot
AlfaPilot is a simple and reliable system based on comparative measure of primary return, S3, and primary
storage vessel temperature, Pt1. AlfaPilot acts as a “piston” effect on the primary storage vessel allowing
fulfilling peak demands of Domestic Hot Water.
If the temperature in Pt1 is higher than the temperature in S3+T (T is settable, default value is 5°C), stored
hot water in the primary vessel will be sent to the boiler/generator or the heating network. The primary vessel
will be filled up with cold water from the primary return, before the AlfaPilot, until measured temperature in Pt1
becomes lower or equal to the temperature in S3 + T.
The colder the temperature is in S3, the more efficient is the AlfaPilot.
Pay attention when making the settings of flow rates and temperature difference on the tap water systems
primary side.
In the case, PT1≤ S3+T, the primary storage vessel is by-passed and heat recovery in the primary storage
vessel goes on with help from solar panels or other renewable heating source, for example heat pump or
geothermal. The 3-port valve opens, and flow goes from AB to A port.
The primary return water enters the modulating
valve in port ‘AB’.
If the water is sufficiently cold, return water flows
through port ‘B’ to the bottom part of the primary
storage vessel.
If the water is too hot, return water flows through
the ‘A’ port, towards the boiler/heat generator.

Installation of a Solarflow unit
6.1 Operating principle Solarflow
In the flowchart RS means a renewable source, eg solar, heat pump, condensate or else recover unit.
The 3-port mixing valve is activated only if temperature in STP or RS is hot enough, to limit DHW over heating
on S1.
Temperature on Pt1 is compared with S2 and allows or not, the primary pump, of the AquaEfficiency, to be
started.
If Pt1< S2+ΔT then the primary pump is stopped. ΔT (DT Recov_Min ) by default 5° is set in 11.14 Solar menu.
Thanks to the AquaEfficiency control, the temperature at S3 is compared with the temperature at S2 to adjust
the primary flow rate and obtain low temperature returns on primary side.
The “leaking flow” on secondary side, coming from the recycling loop, allows S2 sensor to be irrigated and to
keep SolarFlow “awaken” without the need of any flow switch.
If a flow switch must be used because of leaking flow could not be installed, connect it on Remote control
contact terminal or on pump´s start/stop contact.
